--- Comment #15 from Ian Lance Taylor <ian at airs dot com> 2011-07-21 19:56:28 UTC ---
Martin: I was able to reproduce it by configuring using --with-ld to point to a
newly built version of gold configured with --enable-plugins.

Markus: That patch will fix the problem but will do the wrong thing in many
cases, because the division will truncate.

My exact gcc configure line:

--enable-clocale=gnu' '--with-system-zlib' '--enable-shared'
'--with-demangler-in-ld' '--enable-cloog-backend=isl'
'--with-ppl=/home/iant/gnu/ppl-0.11-install'
'--with-cloog=/home/iant/gnu/cloog-0.16.2-install'
'--with-build-config=bootstrap-lto' '--with-fpmath=sse'
'--with-ld=/usr/local/google/iant/gold/gold-objdir/gold/ld-new'
'--enable-languages=c,c++,fortran,java,lto,objc

The ld-new mentioned in the --with-ld option was mainline binutils configured
with:

--enable-gold --enable-plugins

The ppl and cloog mentioned in the gcc configure line were downloaded from
ftp://gcc.gnu.org/pub/gcc/infrastructure.
